ABSTRACT
In Argentina, the Andean biogeographic region accommodates the most diverse population of fleas in the country. The Craneopsyllinae (Siphonaptera: Stephanocircidae) represent one of the most commonly found subfamilies in this region and show some endemism and high diversity. Plocopsylla is the most diverse genus of Craneopsyllinae; it includes 10 species mainly distributed in the Patagonian subregion, which parasitize sigmodontine rodents (Rodentia: Cricetidae). We describe and illustrate the morphology of the aedeagus in species of Plocopsylla that belong to the 'angusticeps-lewisi' complex. This character is of diagnostic value in differentiating among species. A new species of this complex, Plocopsylla (Plocopsylla) linardii sp. n., is described and identified by the shape and chaetotaxy of the distal arm of sternite IX, as well as by the shape of the median dorsal lobe of the aedeagus. New host associations for this complex and range extensions for most of its species are reported. Plocopsylla (P.) silewi is recorded for the first time in Argentina. The southern limits of the distributions of Plocopsylla (P.) lewisi and Plocopsylla (P.) wilesi are extended to Santa Cruz Province. The angusticeps-lewisi complex is found for the first time in San Juan Province. The information may be useful in epidemiological studies of flea-borne diseases.

Smit (1968) misreported Tunga libis from Chile. Here we describe this flea as a new species. We analyzed free life females, male and embedded females. Moreover, we include data about its natural history and biology. These data will allow a better understanding about other Tunga fleas, and particularly for collecting males, which remain unknown to date.

Agastopsylla guzmani n. sp. (Ctenophthalmidae) and Delostichus degus n. sp. (Rhopalopsyllidae) are described. A key is proposed for the genus Agastopsylla; for the genus Delostichus, a brief comparison is made with D. incisus and D. ojedai described after the issue of the Catalogue of Smit (1987).

A new genus and a new species are described from fleas of occupied nest from humming bird, Oreotrichulus estella (d'Orbigny & Lafresnaye, 1838). This taxa shows, in particular, some affinities with Dasypsyllus Baker, 1908, parasite on birds, cosmopolitan except in afrotropical and austral regions, and Smitipsylla Lewis, 1971, parasite on flying squirrels (Anomaluridae) in oriental region.

New taxa, known only by the male, are added to chilio-andean fauna. These fleas belong to sub-genus Neornipsyllus, parasites of Birds, essentially "Passeriforms". D. (N.) huinayensis sp. n. is, inter alia, characterized by the place of large setae on telomere; D. (N.) tapaculensis sp. n. show a tergit XI (or proctiger) unusual for the entire Order by the form and the chaetotaxy composed, essentially, of forked setae.

A new subgenus of Plocopsylla is raised, Schrammapsylla Beaucournu and Ménier from the entire group B of Schramm & Lewis, 1988 and two new fleas from Chile and Argentina are described: Plocopsylla (S.) muruai n. sp. Beaucournu and Gallardo and Ectinorus (E.) mimacydis n. sp. Beaucournu and Gallardo. These two taxa are only known by the male sex.

Based on a collection of approximately 760 fleas, of which 520 were collected in 1994-1995 during scientific studies at the Petit Saut dam site in French Guiana, 12 species and subspecies are discussed. Two taxa, Rhopalopsyllus garbei Guimarães, 1940 and Adoratopsylla intermedia copha (Jordan, 1926), are new records for French Guiana. The fleas collected during the 1994-1995 study were obtained from 35 species of mammals (3,484 specimens); of which, 21 (60%) species were negative for fleas. The mammals were captured primarily by live-trapping during a capture-release study along a portion of the Sinnamary River and its tributaries up to a distance of 70 km upstream from the Petit Saut dam site.
